Application led ."l'uly 20, 1912. Serial No. 710,645.

'b rlZZ whom t may concern Be it known that I, FRANK MUNTZ, a

'citizen of the United' States, .residing at Greenfield, in the county of Greene and State of Illinois, have invented certain new and useful improvements in Plow Attachments, of which the following is a specification, reference being had tothe accompany ing drawings.

This inventionrelates to improvements in plows and more particularly to al plow attachment consisting of spaced rotary disks .to travel in front of the plow point and turn the top soil so that the lower or subsoil turned over by the plow pointwill be turned upon t-he loose top soil,' thus leaving the ground loose and lmellow to receive the seed so thatit will requirebut little further cultivation. j j' j Another object of the invention resides in the provision of adisk attachment for gangV or sulky plows, said attachment comprising spaced disks Y. disposed upon either side of the plow pointiand means for adjustablyV mounting the disks .upon the plow beam whereby the same maybe easily andquickly adjusted with relation tothe plow point.

A still further object ofthe invention resides in the provision of a device of the above character which is simple and durable in construction, efficient and reliable in practical use and may be produced at comparatively small costf l With the above and other objects in view, the invention consists in the novel features of constructionand the combination and arrangement of parts hereinafter more fully `described, pointed out in the claim and shown in the which, Y

Figure 1 is a side elevation of a plow provided with my improved disk attachment. Fig. 2 is a section taken on the line 2 2 of Fig. 1. Fig. 3 is an enlarged secaccompanying drawings in tion taken onthe line 3-3 of Fig. 2, and

and lower the point of the plow so that it will enter the ground to the desired depth.

Upon the plow beam 7, my attachment is arranged, and this attachment comprises the spaced disks S which are preferably of concavo-convex form and may be provided with saw toothed or, smoothedges, as preferred. Between the disks 8, the two part collar 9 is arranged, said collar sections being provided upon opposite sides with the ears 10. A cylindrical sleeve 11 is provided with a concave end to engage closely upon the periphery of one of the collar sections 9, said sleeve being provided at opposite points with ears 12. Through the ears l2 and the Y ears 10 of the collar sections, the bolts 13 are disposed and are provided upon one of their ends with nuts 1&1, whereby the sleeve ll is rigidly held upon the collar.

Revolubly mounted `within the collar 9 is a spool 15 which is provided with enlarged ends 17 engaging the ends of the collar sections 9. VSecured in the spool 1-5, is a bolt 19, as clearly illustrated in Figs. 3 and 4, said bolt being square in cross section and secured at its ends in the hub portions 18 of the disks 8, whereby the spool, rod and disks will all turn together within the collar sections 9. One end of the rod 19 is provided with a head, while a nut 20 is threaded on the other end thereof. ByV adjusting this nut, the hubs of the disks S may be clamped against the ends of the spool 15, thereby securing the several elements together, while permitting of the free rotary movement of the disks.

Preferably, there is an oil groove 16 .formed in the sleeve 11, as best illustrated in Fig. 3, said groove passing down into the collar sections, as shown.

A standard 21 1s provided upon one end 'with a crank 22, and this crank end of the sired to entirely remove the disks for any purposei the same may be readily done by Vsimply loosening the set screws 23 and disconnecting the sleeve ll from the crank 22 of the standard 2l.V A

, From the foregoing, it is believed that the construction and manner of operation of. my

improved plow will be clearly understood.

It will be obvious that any desired number of the pairs of rotary disks can b'e'employed in accordance with the size of the plow. They may be arranged in series in advance of the plow point and adjusted to different #relative .positions with relation to the ground surface so that they will successively cut or slice the soil in layers, thus only leav-` ing the subsoil to be turned over bythe plow. In this manner7 the soil will be thoroughly loosened and placed in condition to receive the seed without necessitating its further preparation. 'Owing to the comparatively few elements employed in my improved diskattachment, it will be readily Uopies of this patent may be obtained for ve cents `eachfoy addressing ythe gifiniinissiner of l?atents,r

apparent that the jentired'device can be produced at small cost and is also extremely preferred, construction and arrangement of the various elements, it will be understood that the invention is susceptible of considerable modification without departing from the essential features or sacriicing any of the advantages thereof. o

llhat I claim is z- Y The herein described .journal bearing embodying a sleeveadapted for attachment to a supporting standard,Y a"cylindrical bearing consisting of two separable sections each provided with oppositely projecting ears, said sleeve beingclosed at one Vend and provided with a concave seating face for en gageinent upon the upper bearing section and having integrally .formed ears vprojectingfroin opposite sides of said concave face Y Y.

to lie in superposed relation to the ears of the bearing, and bolts extending through the ears of the bearing and sleeve tol detachably:

secure lthe :sleeve tothe Abeariirigi and to connect the bearing sections to each other.V

In testimony whereof `I hereuntov affix-my signature in the presence of twojwitnesses.
